; Beit knownlthat I, CnoILMUNRo DYER, a subject of the King of GreatBritain, and

residing atNarbethong, 30 Barring-ton avenue,-Kew, Melbourne, in theState of Victoria, Australia, haveinvented certain new and" usefulImprovement-sin Starters for Internal-Combustion Engines, of which thefollowing is a specification. j

Thisinvention relatesto devices for making a richmixture for startingpurposes in internal combustion engines. It is the object ofthepresentinventionto provide a form of auxiliary carbureter which is onlyintended to to be usedfor starting purposes or in case or emergencies,this carbureter being relied upon entirely topro'vide the mixture forstarting, while the normal running carbureter is cut out of action. Thestarting carbureter is then designed so as to give a rich but uniformmixture in which the fuel is properly vaporized, and for this purposethe carbureter is constructed as hereinafter set forth with reference tothe accompanying drawings, wherein Figure 1 shows the device in sideelevation.

Fig. 2 shows it in end elevation.

Fig- 3 shows the device in partial longitudinal section. 1

A central hollow stem 1 is used having a thin disk 2 at itsendin whichone or more holes are drilled according to the size of the engine andthe amount of fuel required.

The base 5 of the stem fits into the end of a sleeve or socket 3 and isclamped in position by a nut 1. The socket 3 is formed with two holestherein marked 6 and 7 which cooperate with a hole at 8 in a revolublesleeve 9 surrounding the socket 3. The end of the socket 3 is formed asa nut 10 with a projecting hollow stem which is threaded at 11 to engagein the wall of an induction pipe 13, the projecting end being perforatedas at 12 to allow of the escape of the rich mixture into the inductionpipe. The sleeve 9 has an arm 14 projecting therefrom to which anoperating rod is con- ,nected at 15, whereby the sleeve can be 50 turnedin either direction.

In the construction shown the supply of fuel to the device isautomatically controlled by the movement ofthe arm 14 and sleeve 9. 16is a cock controlling the supply of liquid fuel from pipe 17communicating with any suitable source of supply. The

union 18" connects the cook 16 with the projecting face of the hollowstem 1. The arm 19 of the cock engages in a slot in the lever 20[projecting from the sleeve 9;

In operation, assuming the engine to be running, the cock 16 will beclosed and the hole 8 in the sleeve 9 will be opposite the blank wall ofthe socket 3 between the two holes6 and 7. For starting purposes the arm15 is pulled forward causing the hole 8 to register with the hole orslot 6, while the slotted arm 20 engaging the arm 19 of cook 16 turnsthis latter to admit liquid fuel to the hollow stem 1. The suction inthe induction pipe 13 causes air to be drawn out through the holes 12,and the rush of air entering the registering holes 8 and 6 past the endof the stem 1 draws out fuel through the perforated end 2 of the stem,so that the rich mixture is supplied to the induction pipe. In order toassist in vaporizing this mixture 9. roll of wire gauze 21 or the likemay be fitted in the perforated end of the socket member as shown inFig. 3. When the engine picks up on the normal carbureter the startingdevice is thrown out of action by pushing back the arm 14 until the hole8 is returned to the position of Fig. 1. In order to allow of thedrawing to exert a braking action for instance to retard the engine whenrunning down hill,

the arm 14 is moved further while the cook 16 remains closed, until thehole 8 registers with the hole 7. This admits air through the socketinto the induction pipe.

It will. be obvious that the device as above described can be used as astand-by or auxiliary carbureter in the event of defective working ofthe normal carbureter, or where the latter becomes inoperative onaccount of a choked up petrol pipe, for instance.

I claim 1. A priming and starting device for internal combustionengines, comprising a tubular socket member having a hollow perforatedextension adapted to be fitted to an induction pipe and to project intothe same,

- a stem member fitting into said tubular to turn upon the socketmember, with means for operating said sleeve, the sleeve and socketmember having perforations therein which can be brought into and out ofregister by such turning movement;

2. A priming and starting device for internal combustion engines,comprising a tubular socket member having a hollow per forated extensionadapted to be fitted to an induction pipe and to project into the same,a stem member fitting into said tubular socket and formed with aperforation at its end for the egress of fuel, means for rigidlysecuring said stem member in the socket membena cock connected to saidstem member, means for supplying liquid fuel through said cook, a sleeveadapted to turn uponthe socket member, with means for operating saidsleeve, the sleeve and socket member having perforations therein whichcan be brought into and out of register by such turning movement, andinterconnecting means between said sleeve and cook for cutting off thefuel supply when the device is thrown out of action.

3. A priming and starting device for internal combustion engines,comprising a socket havin a hollow end adapted to be fitted to aninduction pipe and to project into the same, said end being perforated,a stem member fitting into said socket and formed with a perforation atits end for the egress of fuel, means for securing said stem member inthe socket member, a cock connected to said stem member, means forsupplying liquid fuel through said cook, a sleeve adapted to turn uponthe socket member, with means for operating said sleeve, one of the saidsleeve and socket members having two apertures therein adapted to bebrought into and out of register with an aperture formed on the othermember on turning said sleeve, and interconnecting means between saidsleeve and cock so proportioned that when one of the said two aperturesis in register with the said single aperture the cock is in the openposition, while when the sleeve is turned further the cock is in theshut position.
